— The Z4M valve is a piloted pressure reducing valve made
as a modular version with mounting surface according to
the ISO 4401 (CETOP PR 121H) standards.
— It is used to reduce pressure on secondary circuit
branches, assuring stability of the controlled pressure and
even changing the flow that runs through the valve.
Ø11.2 (max)
— It can be assembled quickly under the ISO 4401-05
(CETOP 05) directional solenoid valves without use of
pipes.
CONFIGURATIONS (see hydraulic symbols table)
— Z4M*-I: pressure reduction on line P - drainage connected to line T.
— Z4M*-A: pressure reduction on line A and full pressure on line B.
— Z4M*-B: pressure reduction on line B and full pressure on line A.
PERFORMANCES (measured with mineral oil of viscosity 36cSt at 50°C)
Maximum operating pressure bar 320
— It is normally supplied with a countersunk hex adjustment
screw, locking nut and maximum adjustment travel
limiting device.
— It is available in four different pressure adjustment ranges
up to 320 bar.

3 - HYDRAULIC FLUIDS
Use mineral oil-based hydraulic fluids HL or HM type, according to ISO 6743-4. For these fluids, use NBR seals. For fluids HFDR type
(phosphate esters) use FPM seals (code V). For the use of other kinds of fluid such as HFA, HFB, HFC, please consult our technical
department. Using fluids at temperatures higher than 80 °C causes a faster degradation of the fluid and of the seals characteristics.
The fluid must be preserved in its physical and chemical characteristics.
